so I have had a very weird experience just now. I went to update Overwatch, just to have it tell me that I cannot update it because I'm not logged in as administrator. this has never happened before. so I figured shutting down and restarting would fix the issue, just to have my pc boot abnormally (splash screen showing up on multiple monitors, overall much slower boot, getting stuck at splash screen, etc.) I had to do a hard shut down with the power button a couple times, also used the reset button to try to fix it. Upon successful boot, my m.2 is no longer detected. I have tried resetting my bios and nothing changed. Also one other weird thing that happened, the lights on my AIO reset to red, which never happens between power cycles, so not sure what caused that either. The m.2 is a 500gb 970 evo. Also, though my computer is booting now, it is booting at 1/4 the speed it used to. (obviously the m.2 is not my boot drive) so i'm confused as to why it is booting abnormally, as well as the drive not being detected. If anyone has any thoughts on possible remedies I would greatly appreciate it. oh, also Overwatch was installed on the m.2. so i have suspicions something was wrong when it gave me the administrator prompt.
Update: I removed the m.2, and booted. The boot process returned to normal, no splash screen issues and it booted at the proper speed. I then powered down, reseated the m.2, and all the issues came back, slow splash screen, slow windows loading screen, and drive is still not detected. so my m.2 is the culprit behind the start up issues, on top of not being detected.
